The program that computes the discriminant for the equation 
 4x + 5 = 0 is:
 4x + 5 = 0 is:
Class Name: Exercise01_01Extra
public class Exercise01_01Extra {
public static void main(String[] args) {
System.out.println(4 4 - 4 3 * 5);
}
}
It can also be done with:
Python
class Exercise01_01Extra:
 def discriminant(self, a, b, c):
 """
 Calculates the discriminant of a quadratic equation ax^2 + bx + c = 0
 """
 discriminant = b ** 2 - 4 * a * c
 return discriminant
if __name__ == "__main__":
 # Create an instance of the class
 exercise = Exercise01_01Extra()
 # Assign coefficients of the quadratic equation
 a = 3
 b = 4
 c = 5
 # Calculate the discriminant
 discriminant = exercise.discriminant(a, b, c)
 # Print the discriminant
 print("The discriminant is:", discriminant)
